Which of the following rock structures is/are fold(s)?

Which of the following statements is/are CORRECT for the M-plane of any fault?

In the fold profile section shown in the figure, 1 and 3 are the oldest and the youngest stratigraphic units, respectively. Which one of the following fold descriptions CORRECTLY matches the asymmetric fold shown in the given figure?

The given outcrop pattern on a flat topography represents:

At a certain depth in the crust, the maximum and minimum principal compressive stresses are 150 MPa and 75 MPa, respectively, which lead to normal faulting. If the average density of the crust is 2700 kg/m$^3$, the crustal depth of fracture initiation according to Anderson's theory of faulting is ................ km. (g = 10 m/s$^2$) [round off to one decimal place]

Which of the given folds is/are represented by the stereoplot? \begin{center} \includegraphics[width=0.5\textwidth]{04.jpeg} \end{center}

In a zone of active normal faulting, the maximum and minimum in situ principal stresses (compressive in nature) are 30 MPa ($ \sigma_1 $) and 10 MPa ($ \sigma_3 $), respectively. The fault plane striking N-S has a dip amount of 60° towards E. Considering Anderson theory of faulting and using the given information, the calculated normal stress on the fault plane is $\underline{\hspace{1cm}}$ MPa. (in integer)

The given outcrop pattern of a bed (shaded in grey) with respect to contours (dashed lines) indicates that the bed

With regard to superposed folding, the stereographic projection represents a geometry of:

A vertical borehole encounters a shale bed of uniform thickness occurring at a depth of 5 m and dipping 60°. The borehole pierces through this shale bed for a length of 10 m to reach a sandstone layer below. The true thickness of the shale bed is $\underline{\hspace{1cm}}$ m.
